Tab Accordion

Description

Tab groups with an active tab will be automatically expanded, whilst tab groups that do not have an active tag will be contracted.

Also tabs opened from a link within a tab group will be located within the originating group (optional).

Known issues:- Extension will not work in Opera 11 and earlier- Dragging a tab to create a new group will confuse Opera. The group will be contracted but behave as though it's expanded. This seems to be a bug with opera and is corrected when the group is contracted again.- The expanding and contracting of groups when adding our removing a tab is triggered when a tabs position change. But a tab can be added to or removed from a group without its position changing which will prevent the groups from expanding/contracting automatically.

Only complaint is new tabs no longer appear next to the current active tab and instead appear at the end of the stack. This is undesirable when cloning a tab or opening a link in a background tab, logically these new tabs should be grouped near the active tab and not separated. The AutoStack extension has this functionality.
